As you probably already know, PHP 7 is a thing, and it's coming this year! Which makes this as good a time as any to go over what's new and improved. In the first part of this series, we looked at the some of the most important inconsistency fixes coming up in PHP 7 as well as two of the biggest new features. In this post, we take a look another six big features to land in PHP 7 that you'll want to know about.

The features he talks about this time are:

What to Expect When You're Expecting PHP 7, Part 1
April 03, 2015 @ 08:28:36

Davey Shafik has posted the first part of a new series about PHP 7 on the Engine Yard blog today - What to Expect When You're Expecting: PHP 7.

As many of you are probably aware, the RFC I mentioned in my PHP 5.0.0 timeline passed with PHP 7 being the agreed upon name for the next major version of PHP. Regardless of your feelings on this topic, PHP 7 is a thing, and it's coming this year! With the RFC for the PHP 7.0 Timeline passing almost unanimously (32 to 2), we have now entered into feature freeze, and we'll see the first release candidate (RC) appearing in mid June. But what does this mean for you?

He gets into some of the details of what you can expect to see in this next major release including:

  • Inconsistency Fixes
  • Performance
  • Backwards Incompatible Changes
  • Scalar Type Hints & Return Types
  • Combined Comparison Operator (spaceship)

He ends the post hinting at other things to come in part two of the series including six other big features you need to know about to upgrade to PHP 7.

Cody Kennedy-Darby:
Testing Your Current Code Against PHP7 Or HHVM
April 01, 2015 @ 08:49:11

On Medium.com Cory Kennedy-Darby has a quick post showing you how you can test your current code against the latest versions of PHP 7 with the help of DUnit.

DUnit (dee-unit) makes your life easier by allowing you to run your unit tests on different versions of PHP or HHVM. Different versions are possible by using Docker containers. Thanks to @danbruce each of the Docker containers are only, ~35 MB in size. [...] PHP7 isn't that far away. In fact, it is scheduled for release in ~8 months in November. Now is the perfect time to start testing your code against PHP7 nightly.

He starts with a few reasons you might want to test your code and things you can do to start "thinking forward" to when it is released. He then shows you how to install DUnit (more detail here) and use it to test on both PHP 7 and HHVM builds.

Rob Allen:
Building and testing the upcoming PHP7
March 30, 2015 @ 10:14:08

Rob Allen has posted a guide to building and testing PHP 7, the next upcoming major build of the PHP language (released sometime later this year).

The GoPHP7-ext project aims to ensure that all the known PHP extensions out there work with the upcoming PHP 7. This is non-trivial as some significant changes have occurred in the core PHP engine (related to performance) that mean that extensions need to be updated. In order to help out (and prepare my own PHP code for PHP 7!), I needed the latest version of PHP7 working in a vagrant VM. Fortunately Rasmus has created a such a VM called php7dev, so let's start there.

He walks you through the process of grabbing the latest version of the virtual machine and set it up as a Vagrant VM instance. He talks about the different PHP versions contained in the VM and how to update PHP 7 to the latest pre-release version. Finally he talks about building an extension on the VM (he uses the apfd extension) and how to configure the VM to be able to test your own code too.

Zend:
5 Things You Must Know about PHP 7
March 27, 2015 @ 11:07:39

There's been a lot of talk in the community about PHP 7 and what features will be included but there's been a *lot* of it. To help distill it down a bit Zend has posted this infographic of the Top 5 features that will be coming in this next major version.

Their top five list includes both the main points and a quick summary for:

  • When it comes out (hint: this year)
  • The spaceship operator
  • Return type declarations and scalar type hints
  • Performance improvements

...and #5, even more performance improvements. There's also some links to other information about some of the topics to provide even more detail for those wanting to dive in.

Remi Collet:
PHP 7.0 as Software Collection
March 26, 2015 @ 10:15:48

Remi Collet has a new post today talking about the next major release of the PHP language - PHP 7 - and how it, in its current state, can be installed now as an RPM from the "remi" repository as a software collection.

RPM of upcoming major version of PHP 7.0, are available in remi repository for Fedora 20, 21, 22 and Enterprise Linux 6, 7 (RHEL, CentOS, ...) in a fresh new Software Collection (php70) allowing its installation beside the system version. As I strongly believe in SCL potential to provide a simple way to allow installation of various versions simultaneously, and as I think it is useful to offer this feature to allow developers to test their applications, to allow sysadmin to prepare a migration or simply to use this version for some specific application, I decide to create this new SCL.

Instructions for the installation (via yum) are included and a list of some things "to be noticed" about the setup are also included.

PHP7 More strict! (but only if you want it to be)
March 18, 2015 @ 10:48:38

In this new article Er Galvao Abbott talks about the struggle (and finally, inclusion) of type hinting in PHP, more specifically coming in PHP7, and how strict they can be.

It wasn't easy (we knew it wouldn't be) and certainly wasn't pretty (we sort of knew that as well), but it's finally official: PHP7 will come with Scalar Type Hints (STH) and an optional "strict mode". [...] This is basically a step towards a more strict way of coding in PHP. Will we see more steps in that direction in the future? We don't know and we're OK with that for now. What's brilliant about the body of work represented by these RFCs is that by implementing their concepts and specially making the "strict mode" optional the choice of being more strict remains with the programmer.

He talks some about the background of the want and need for strict typing in PHP and mentions three RFCs that will influence the type hints and handling in PHP7:

He summarizes each RFC and what it contributes to the language. He ends the post by dispelling one thing about all of this new typing functionality - PHP will remain loosely typed, this new functionality is in a "strict mode" only used when specified.

Phil Sturgeon:
PHP 7 Feature Freeze
March 16, 2015 @ 09:04:44

Phil Sturgeon has a new post to his site looking at the PHP7 feature freeze for this upcoming major PHP release (implemented as of yesterday, the 15th). In it he provides a list of features, their related RFCs and how likely they are to make it into PHP7.

Today was the feature freeze for PHP 7. That means no new votes can be started for a feature that is aimed at PHP 7.0, and would instead have to go into PHP 7.1. Instead of heading out to St Patric's Day with a bunch of New Yorkers making dubious claims about their tenuous connection to Irish ancestry as an excuse to drink, I thought it would be a good time to review some of the more recent RFCs that made it in, and those that didn't.

His list includes:

  • Remove PHP 4 Constructors
  • Spaceship Operator
  • Replacing current json extension with jsond
  • Skipping Optional Parameters for Functions
  • Constructor behaviour of internal classes
  • Reclassify E_STRICT notices

Each one has a link to the current version of the RFC, the current status and Phil's own opinion of the feature (usually just one word).
